4 years ago Hi @reckoner, thank for trying out jupyter-dash.
We'll need a bit more information to help. In particular:
jupyter-dash?To try out examples, you can also run jupyter-dash using binder:

4 years ago jupyter notebookconda install -c plotly jupyter-dashYes. I tried the binder and it looked great! I also downloaded the IPYNB from the binder and tried it locally, but no such luck.
Thanks!

4 years ago I was getting this primary error with the demo code that the OP referenced!
ConnectionRefusedError: [WinError 10061] No connection could be made because the target machine actively refused it
and the secondary error
_ConnectionError: HTTPConnectionPool(host='127.0.0.1', port=8050): Max retries exceeded with url: /_alive76071299-760d-44ff-82d5-83aca0100737 (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x000001F28514E348>: Failed to establish a new connection: [WinError 10061] No connection could be made because the target machine actively refused it'))
I set debug to False in run_server(...) to fix my error:
app.run_server(mode='inline', debug=False)I appreciate that the OP's error message is different (yet similiar?) but that may be because of different environment setups? :
Anyway, its worth a try - apologies if I got it wrong and hijacked this thread!

4 years ago Hi, I have a similar error on my Mac Os X 10.14.6 with Anaconda (python 3.7.7) both in Jupyter notebook and jupyterlab.
The line JupyterDash.infer_jupyter_proxy_config()does not help. On the notebook it doesn't do anything on lab it does not block the system but has always an asterisk (*) on the cell.

socket.gaierror: [Errno 8] nodename nor servname provided, or not knownSOLVED Dash uses a weird hostname. I just added that name to /etc/hosts and now it works.

4 years ago Thanks @adalseno, for the benefit of others would you mind share the entry that you added to /etc/hosts to get things working (anonymizing whatever values you'd like of course)? Thanks!

4 years ago The code to add to /etc/hosts is as follows (you must use sudo to update that file):
# Added for dash on python-jupyter
127.0.0.1 x86_64-apple-darwin13.4.0The name may vary depending on you environment but if you start Dash from a python script it will output the name to use like this:
Dash is running on http://x86_64-apple-darwin13.4.0:8050/

4 years ago If you don't have sudo priviledges and are running remotely, I was able to just specify host name:
app.run_server(mode="inline", host = "localhost")

3 years ago In JupyterLab running under JupyterHub on AKS I was getting:
After changing to app.run_server(mode="inline", host = "localhost") I then got a "localhost refused to connect" error:
Edit: Calling _send_jupyter_config_comm_request before importing JupyterDash fixed that problem so it now works for me! :tada:

@adalseno I am facing this error in visual studio, What should I do to resolve this error??
I'm trying to run the demo code as shown here
